Can You Have Cataract Surgery If You Have Glaucoma?

A glaucoma diagnosis often comes with a routine that includes daily drops, pressure checks, and visual field tests every few months. So when your eye doctor mentions that a cataract is also forming, it can often feel like one problem now stands in the way of fixing the other. The reality is actually closer to the opposite!
Keep reading to learn what you need to know about cataract surgery when you have glaucoma!
Glaucoma and Cataracts Are Two Different Problems
Glaucoma harms the optic nerve at the back of your eye, usually because the pressure inside your eye gets too high. Your eye is always making fluid and draining it through a channel called the drainage angle. If this channel cannot keep up, pressure rises and damages the optic nerve. Glaucoma gets worse over time and cannot be cured, so treatment aims to lower the pressure and keep it down.
A cataract affects how clearly you see and how well your eye focuses, and it happens near the front of the eye. The natural lens, which is clear when you are young, slowly becomes cloudy as you age and scatters light instead of focusing it. This causes common cataract symptoms like faded colors, halos around lights, and feeling like you never have enough light to read.
Treating one of these conditions does not solve the other. Cataract surgery removes the cloudy lens but does not treat glaucoma. Glaucoma drops and laser treatments protect your optic nerve, but they cannot get rid of a cataract. Each problem needs its own treatment.
If you have glaucoma, it does not make cataract surgery more dangerous for your optic nerve, and it does not need to delay your decision to move forward. Cataract surgery can continue on its own timeline while glaucoma is monitored and treated separately, whether that means eye drops, laser treatments, or a referral for further glaucoma-specific care. Since both conditions are common as people get older, many patients in their seventies and eighties have both at once.
How Cataract Surgery Can Affect Your Eye Pressure
As you age, your natural lens becomes thicker, harder, and cloudier. When a cataract forms, the lens can get so bulky that it crowds the drainage angle. An artificial lens is much thinner, so replacing the cloudy lens with a new one creates more space and helps fluid drain better. Some people notice their eye pressure drops a bit after surgery for this reason.
This pressure-lowering effect is one reason cataract surgery sometimes comes up in the conversations about glaucoma care, even though the two remain separate treatments handled on their own timeline.
What Is MIGS?
MIGS means minimally invasive glaucoma surgery. These are procedures that lower eye pressure by helping the eye drain fluid better, instead of making a large new drainage path like traditional glaucoma surgery. The methods are different, but the goal is the same.
Compared to a trabeculectomy or a drainage tube, MIGS is easier on the eye, has fewer complications, and heals much faster. However, it usually lowers pressure less, so it is best for mild or moderate glaucoma.
Glaucoma specialists perform surgical procedures for glaucoma treatment, which are distinct from cataract surgery. The eye surgeons at Lalin Eye focus on the cataract procedure itself and coordinate with your glaucoma specialists for any surgical glaucoma treatment you may need.
Managing Glaucoma Alongside Cataract Surgery
Having cataract surgery does not put glaucoma treatment on hold. You will continue with regular pressure checks and visual field testing, and your eye doctor will keep managing glaucoma with drops or other appropriate treatment, since glaucoma is a lifelong condition that surgery alone does not cure.
Deciding When to Have Cataract Surgery
A cataract diagnosis does not have to wait for glaucoma to reach some ideal point first in most cases. If blurred vision, glare at night, or needing more light to read are affecting your daily routine, that is reason enough to talk with your eye doctor about surgery. Your glaucoma treatment stays on its own schedule, whether that means your current drops, a laser treatment, or an adjustment that your glaucoma specialists recommend.
